What is the piezo nanopositiong stage?
Piezoelectric nanopositioning stage is piezoelectric platform that uses piezoelectric ceramics as driving source and combines with flexible hinge mechanism to achieve precise movement of X/Z/XY/XZ/XYZ axes. The maximum motion range is up to 375μm. It has the characteristics of small volume, no friction, and fast response speed. It is equipped with high-precision sensors, which can achieve nano-level resolution and positioning accuracy and have extremely high reliability. Piezoelectric nanopositioning stage plays vital role in the field of precision positioning.
Features of piezo nanopositioning stage
High resolution
Piezoelectric nanopositioning stage uses frictionless flexible hinge guide mechanism, which can achieve sub-nanometer resolution. CoreMorrow N60.X series piezoelectric nanopositioning stage, with E53 series piezoelectric control, can achieve 0.5nm step resolution.
Large blocking force
CoreMorrow fast tool servo stage uses large blocking force piezoelectric ceramics, with maximum force of several thousand newtons, which is widely used in precision machining and other fields.
Quick response
Piezoelectric nanopositioning stage is driven by piezoelectric ceramics, and the response time can be as fast as milliseconds. CoreMorrow N65 series nanopositioning stage is equipped with high-power E00/E01 series piezoelectric controller, which can achieve full amplitude step time of 1.5ms.
No wear
The stage adopts finite element simulation analysis to optimize the flexible hinge structure. The flexible guidance system has ultra-high guidance accuracy, and has the characteristics of high rigidity, high load, no wear, and maintenance-free.
Voltage driving
CoreMorrow standard driving voltage for piezoelectric nanopositioning products is 0~120/150V, which can produce a maximum displacement of 375μm. At the same time, other voltage driving versions can be customized according to requirements.
